Design the next chip on software built for speed
Great Attractor is a desktop platform for CPU, GPU and SoC architecture, simulation and verification — native on Windows, Linux and macOS, with engines written end to end in the Sigma programming language.

Platform status
Status is published honestly and updated as each gate passes. No benchmark is shown before it has been measured on a recorded setup.
Built in Sigma
Sigma compiles to machine code with memory safety and explicit effects, and was designed so the compiler can prove away checks in hot loops. Great Attractor engines, the desktop platform and its services are Sigma; the only exceptions are installers and this website.
Product families
Eight families on one Sigma platform, in build order. Chip architecture ships first because it helps CPU, GPU and SoC teams before foundry signoff is required; later families light up as their correlation benchmarks pass.
One platform, every engine
Architecture exploration, RTL verification, synthesis, timing, physical design, analog and device physics, packaging and multiphysics share one project model, one viewport and one job system — so a change in architecture can be re-simulated downstream without file-format gymnastics.
